Product Demos in Onboarding Emails

August 18, 2026

Most signups never come back after the first session, and email is the only way to reach them once they have gone.

Onboarding sequences usually fail because they describe features to someone who has not yet succeeded at anything. A demo changes what those emails can be.

The email cannot run the demo

No mail client will run an interactive demo -- iframes and scripts are stripped everywhere, and that is not going to change. Anyone promising otherwise is describing an animated GIF.

What works is a real screenshot of the first step with a play affordance drawn on it, linked to the demo. The whole image should be the link, because people click the picture rather than hunting for text.

A sequence that respects where they are

  • Day 0: one demo of the single fastest path to a first result. Not a tour, not a feature list.
  • Day 2, if they have not returned: the same outcome framed as a problem they have -- different subject, same demo.
  • Day 5: the second most common use case, for people who did return but only did one thing.
  • Day 10: a short demo of the feature that correlates with retention in your data, whatever that is.

Segment on behaviour, not on time

Someone who has already completed the flow in your day-0 demo should not receive it again on day 2. That is the single most common onboarding email mistake, and it reads as an email programme that is not paying attention.

If you can only branch on one signal, branch on whether they have performed the core action. It matters more than every other segmentation combined.

What to measure

Not opens, which are unreliable now, and not clicks alone. The number that matters is whether people who clicked the demo went on to perform the action it showed.

That is the whole hypothesis of onboarding email, and it is measurable if the demo link carries a parameter you can tie back to the account.

Frequently asked questions

Can you embed an interactive demo in an onboarding email?
No. Mail clients strip iframes and scripts universally. Use a real screenshot of the first step with a play affordance drawn on it, linked to the demo, and make the whole image the link since people click the picture rather than hunting for a text link.
What should the first onboarding email contain?
One demo of the fastest path to a first real result -- not a product tour and not a feature list. A user who has not yet succeeded at anything has no context for features, and a tour asks them to invest attention before they have any reason to.
How should onboarding emails be segmented?
On behaviour rather than time. If you can only branch on one signal, branch on whether the user has performed the core action -- sending someone a demo of something they already did is the most common and most obvious onboarding mistake.
